Ok, but, , 

1) I suspect that you could form variations on ice-iii at lower pressures
using additives in solution with the water.  My question is sir does
anyone know whether or not physical experiments have been done to
investigate the phase change with additives.

2)  I strongly suspect that the damage to the tissues can be vary rate
dependent, and highly dependent on partial pressures of gases disolved in
your working liquid.  As in how fast do you apply/ drop the pressure and
whether you have any gas bubbles in the system.  I have done some
experiments along these lines at LSU while a graduate student there.  I
pressureized mouse embryos to ~ 30,0000 psi.  We the dropped the pressure
and examined the embryos under microscope.  The damage was very extensive,
and characteristic of explosive decompression in my opinion and that of
some biology grad students I was working with.  My technical problem at
thetime was that I could not make a mechanism (within my out of pocket
budget.) that could deliver or drop those pressures at a slow rate.

Can you please tell me whether some work has been done in those areas and
where it might be published.
